HANDLE FOR SLIDING WINDOW Filed Jul 24. 195&

3 Sheets-Sheet 3 IN VEN TOR.

AerHu/a ML/MMENDEY BY A TTOENEYS Stes The present invention relates to awindow having sliding sashes, and in particular to the construction ofhandles for the sashes which cooperate in a novel manner with the siderails between which the windows slide, to the end that the sashes may beretained in desired adjusted position, may readily be moved to a newposition, may be locked in position, and in a preferred embodiment, maybe removed from between the rails.

Windows with vertically slidable sashes have long been in common use. Aprime requisite of such windows is that the sashes, which are guided inand slide vertically between the side rails of the window frame, shouldbe adjustably positionable in a variety of locations so as to providefor the desired degree of ventilation or access through the windowopening. With changes in climatic conditions or for other reasons thepositions of the sashes must be readily adjustable, and it is mostdesirable that said adjustment should require as little manipulation aspossible. The optimum mode of adjustment is merely to slide the windowto its desired position. With counterbalanced sashes which are more orless frictionally received within the side rails, no particular problemis involved. With uncounterbalanced sashes, however, such as arecommonly used in the aluminum windows of today, the force of gravityacting on the sashes tends always to move them to their lowermostpositions. Means must be provided for preventing this. These meansusually comprise catches mounted on the window sash which engage withappropriately shaped structure on the window frame. It is often the casethat these catches, which prevent the sash from moving downward, mustalso be disengaged from the frame when the sash is to be moved upward.This extra manipulative step is a decided drawback.

Means must also be provided for locking the window sashes againstunauthorized movement in either direction in order to maintain thesecurity of the interior of the room of which the windows are a part. Inconventional windows this locking edect can be accomplished only whenall the sashes are fully closed. This, too, represents a disadvantage,since it may be desired to have the windows slightly open during thenight to provide for ventilation of the room. It is most desirable ifthe sashes could be locked in position to provide for such ventilationand at the same time prevent unauthorized entry of intruders from theoutside.

Furthermore, and particularly with aluminum windows, it is desirablethat the individual sashes be re movable from the window frame forcleaning and replacement.

ln accordance with the present invention the sash, the framework ofwhich is here specifically disclosed as formed of aluminum extrusionsand which slides within a frame also formed of aluminum extrusions, isprovided with a pair of handles which secure it to the window frame andwhich cooperate with the window frame, when in a first operativeposition, to permit the sash to be retained in a selected one of aplurality of adjusted positions, and to be moved in one direction(preferably upwardly) without having to readjust, reposition or manuallymanipulate the handles in any way. To move the window in the oppositedirection (preferably downwardly) one merely need press inwardly on thehandles at right angles to the plane of the window. When the handlesatent are located in a second operative position the sash is locked, andcannot be moved either upwardly or downwardly unless the handles arepressed inwardly. Preferably the handles can also be moved to a thirdoperative position in which they become disengaged from the rails, thuspermitting the sash to be swung out from the frame or completely removedtherefrom. The handles are normally retained in the first operativeposition above described by reason of a detent engagement betweenthemselves and the sash, but they may be moved to either of their otheroperative positions by pressing inwardly thereon to disengage thedetent. 7

These results are achieved, in the form here specifically disclosed, byslidably mounting the handles on the sash so that they are movableoutwardly toward the side rails of the frame and inwardly away therefrombetween operative positions, the handles also having a limited degree ofmovement in a direction at right angles to the plane of the sash,resilient means being active on the handles to urge them in onedirection of that limited degree of movement, preferably outwardlytoward the front of the window facing the inside of the room. Thehandles have portions adapted to extend out laterally from the sashesand be received within appropriate structure on the side rails of theframe, that structure having recesses into which the outwardly extendinghandle portions are urged by the resilient means. The outwardlyextending handle portions have an outer part and an inner part which aredifferently configured. When one of those parts is received within arecess in the side rail, as will be the case in the first operativeposition of the handle as I above set forth, it will cooperate with thatrecess, as by means of an abrupt wall engaging an abrupt edge of therecess, to prevent movement of the sash in one direction (preferablydownwardly) unless and until the handle is pushed in (toward the rear ofthe window, as disclosed) against the action of the biasing means, suchinward movement of the handle causing the handle part to move out fromthe recess. The opposite wall of the handle part under discussion willcooperate with the recess, as by having a cam surface formed thereonwhich engages with the corresponding recess edge, so that when the sashis moved in the opposite direction (upwardly) the handle portion will becamrned inwardly against the action of the resilient means and thusescape from the recess, thereby permitting the sash to be moved upwardlywithout having to manually manipulate the handle in any way. The secondhandle part, which is positioned in the side rail recess when the handleis in its second operative position as above described, will cooperatewith that recess, as by having abrupt walls on both sides thereofengageable with the correspondingly abrupt edges of the recess, so as toprevent movement of the window in either direction unless and until thehandle is pressed inwardly against the action of the resilient means.The handle may have a third operative position in which the handleportion is retracted to a degree sufiicient so that it no longeroperatively engages its corresponding side rail, thus freeing thatportion of the sash to which the handles are attached (usually the lowerportion thereof) from the frame and permitting the sash to be swung outor removed from the frame.

Thus a simple and sturdy handle may be inexpensively produced andassembled with the sash, that handle permitting, through manipulationthereof, the selection of a desired condition for the sashes-one inwhich the sashes may be lifted merely by urging them in that direction,or one in which the sashes may not be moved in any direction unless thehandles are appropriately manipulatedan also permitting the sashes to beremoved from the window frame whenever that is desired. The sashes maybe locked against movement up or down even when'they are notincompletely closed position, thus providing for a high degree ofsecurity without sacrifice of flexibility in ventilation.

To the accomplishment of the above and to such other objects as mayhereinafter appear, the present invention relates to the construction ofa slidable sash window and of handles for the sashes thereof as definedin the appended claims and as described in this specification, takentogether with the accompanying drawings, in which:

The window as here disclosed comprises a frame generally designated Aand three sashes generally designated B, C and D vertically slidablewithin the frame. The frame comprises side rails 2 and 4 and top andbottom rails 6 and 8, each of the rails being formed with three channels10, 12 and 14 extending rearwardly from the front Wall 16 of the framewhich is adapted to be directed inwardly into the room. Each of thechannels has a front surface a and rear surface 11, and recesses 18 areformed in the front surfaces (1 of the channels 10, 12 and 14 atpredetermined positions therealong, these recesses 18 being provided inopposed pairs in the channels in the side rails 2 and 4. The side andtop rails 28 may conveniently be formed from aluminium extrusions, therecesses 18 thereafter being produced by a suitable machining operation.

Each of the sashes B, C and D we composed of side frame pieces 20 and 22and top and bottom frame pieces 24 and 26 which carry a central panel.In the sashes B and C this central panel comprises a pane of glass 27,while in the sash D the central panel comprises a screen 28. The sashesB, C and D may all be of substantially the same height, but they differin width. One of the sashes, here disclosed as the sash B, is the widestand slides between the narrow front walls *30 which define the front ofthe channels 10. The sash C is somewhat narrower than the sash B so asto slide between the front walls 32 of the channels 12. The sash C isthe narrowest of the three sashes and slides between the front walls 34of the channels 14.

The bottom frame pieces-26 of the sashes B, C and D are provided withapertures 36 extending inwardly from the sides thereof, those aperturesbeing defined by the rear walls 38, the side walls 40 and the frontwalls 42 of the frame pieces 26, slots 44 being provided in the frontwalls 42 which expose but are narrower than the apertures 36. Recesses46 are formed in the front wall 42 extending upwardly and downwardlyfrom the slots 44.

The handles, generally designated E, are adapted to be received withinthe apertures 36 so as to be slidable laterally therealong toward andaway from the side rails 2 and 4. The depth of the apertures 36 istherefore greater than the thickness of the handles B. Each handle Ecomprises an elongated body 48 of appropriate structural material suchas aluminum the width of which is less than that of the aperture 36 inwhich it is to be received but greater than that of the slot 44 whichexposes the interior of the aperture 36. An intermediate portion ofthe'body 43 may be cut away at 50 to provide a finger opening exposedthrough the slot 44. A central longitudinal part 52 of the handle israised from the body 48 and has a width such that it can pass throughthe slot 44, and it carries a pair of ears 54 which may be receivedwithin the'recesses 46.

The handle E has an end portion generally designated 56 which is adaptedto extend out laterally from the sash frame piece 26 through an end ofthe aperture 36. The handle portion 56 comprises an outer part 58 and aninner part 60, both disclosed as raised from the body 48 and having awidth somewhat less than the width of the recesses 18 in the channels10, 12 and 14. The outer part 58 has an abrupt lower edge 62 and aninclined or cammed upper edge 64. The part 60 has an abrupt lower edge66 and an abrupt upper edge 68. The upper and lower edges of therecesses 18 are also abrupt.

interposed between the handles E and the bottom walls 38 of theapertures 36 is a bowed resilient leaf spring '70 which acts as aresilient biasing means urging the handle E toward the top wall 42 ofthe aperture 36, the raised portion 52 of the handle E thus moving intothe slot 44. One end 72 of the spring 70 may be upbent and receivedwithin a recess 74'formed in the undersurface of the handle body 48.

The handles E, together with the springs 70, are inserted into theapertures 36 in the bottom frame pieces 26 of the sashes B, C and Dthrough the open lateral ends of the apertures 36 until they aresubstantially completely received within those apertures. Tabs 76 (seeFIG. 14) may be struck up from the bottom Walls 38 to serve as positivestops limiting the laterally inward movement of the handles 8. The upperends of the sashes B, C and D are provided with lugs 78 which may the bepositioned in the appropriate channels 10, 12 or 14. The sash is thenswung into the plane of the frame A, after which the handles E are slidlaterally outwardly toward the side rails 2 and 4 until the cars 54 onthe handles E come opposite the recesses 46, at which time the action ofthe spring 70 will cause the ears 54 to snap into the recesses 46. Thiswill arrest the laterally outward movement of the handles E in positionssuch that the outer handle parts 58, but not the inner handle parts 60,enter the appropriate channels 10, 12 or 14. (See FIGS. 4 and 8, andsash D in FIG. 1.)

When a handle E is in this position the action of the spring 70 willurge it forwardly toward the wall 42 and hence, when the handle part 58registers with an exposed recess 18 in the front wall of the channel,the spring 70 will urge the handle part 58 into that recess 18 (see FIG.9); Engagement between the abrupt bottom wall 62 of the handle part 58with the abrupt bottom edge of the aperture 18 will prevent downwardmovement of the sash wall unless and until the handleE is moved inwardlyin a direction at right angles to the plane of the window and againstthe action of the spring 70 for a sufiicient distance to remove thehandle part 58 from the recesses 18 (compare FIG. 13). This may readilybe accomplished by pressing on that portion of the handle E adjacent thepart 58 which is exposed through the slot 44.

However, with the handle E in its operative position shown in FIGS. 4and 8, if one wishes to raise the sash all that one need do is move itin that direction. As may be seen by comparing FIGS. 9 and 10, when thesash is thus moved the upper inclined camming wall 64 of the handle part53 engages with the upper edge of the recess 18 and forces the handle Einwardly against the action of the spring 70, thereby removing it fromthe recesses 18 and permitting the sash to move upwardly.

When it is desired to lock a sash in a desired position, so that itcannot be moved upwardly except when the handles E are appropriatelymanipulated, the handles are pressed inwardly toward the rear of thewindow against the action of the spring 70 and then moved laterallyoutwardly to the position shown in FIG. 11 (and see sash C in FIG. 1),in which position the inner handle part 60 enters the channel 10, 12 or14 so as to be received within an appropriate recess 18 when the sash isproperly vertically positioned. The handle part 60 has upper and loweredges 66 and 68 which are both abrupt, and consequently the handle part60 will prevent movement of the sash either upwardly or downwardlyunless and until the handle E is pressed inwardly against the action ofthe spring 70 (compare FIGS. 12 and 13).

When the sash is to be unlocked the handles E are engaged in anyappropriate manner, as by means of the finger recesses 50, and slidlaterally inwardly until the ears 54 snap into the slots 46, there urgedby the spring 70. The handles E will then be in their first describedoperative position in which the sashes may be lifted without having tomanipulate the handles.

If one desires to remove a sash from the frame all one need do is pressthe handles E inwardly against the action of the springs 70 and thenmove them laterally inwardly to the positions shown in FIG. 14 (and seesash B in FIG. 1), in which the handle end portions 56 are completelydisengaged from the channels 10, 12 or 14, after which the sash may beswung outwardly and then pivoted so as to disengage its lugs 78 from theappropriate channels.

The handles E are accessible only from the front of the window, which isdirected inwardly into the room of the window forms a part.Consequently, particularly when a three-sash window such as is heredisclosed is involved, and where one of the sashes carries a screen 28,the window may be opened and locked at the same time so as to provide anappreciable degree of security against unauthorized entry through thewindow. This is, of course, of considerable importance for downstairs orground level bedrooms in private homes. For example, the upper part ofthe window can be closed by the sash B, and the lower glass pane sash Ccan be raised to an intermediate position to permit air to pass throughthe window, both of the sashes then being locked by sliding theirrespective handles E outwardly. Pressure on the sashes from the outsideof the window therefore will be ineffective to cause them to move fromtheir locked positions. In order to prevent a would-be intruder frominserting his hand through the open portion of the window and reachingup to manipulate the handles E, the screen sash D may be moved tocompletely cover the opening left by the sash C, the screen sash D thenbeing locked in position.

The handles E can be very inexpensively manufactured, as by a diecasting operation. They are preferably monolithic in structure, and arehence extremely sturdy and reliable. They are very easily assembled withthe window sashes, and when assembled function in a substantiallyfoolproof manner. They provide for a high degree of freedom inmanipulation of the windows and, when moved to locked position, reliablyperform their locking function.
